Petunias, Angelonias and Hibiscuses

It’s summer at the Trials Gardens at UGA and there are plenty of plants on which you can feast your eyes. But while we’re strolling through the gardens, let’s take a look at some of the highlights this year in petunias, verbenas and hibiscuses.

Petunias

There are probably more than 150 petunias here in Georgia. Among the top-performing petunias are:

– ‘Suncatcher Pink Lemonade’

– ‘Purple Vein Ray’

– ‘Surprise Black Jack’

– ‘Potunia Yellow’

– ‘Supertunia Vista Bubblegum’

– ‘Whispers Red’

I’ve always enjoyed Danziger’s ‘Sun Ray,’ but I’m also impressed with ‘Purple Vein Ray’–especially as a container combination like the one UGA planted with Floranova’s ‘Field of Dreams’ ornamental corn.

‘Supertunia Vista Bubblegum’ from Proven Winners works well with other plants in containers, too. In the trial gardens, I tried ‘Vista Bubblegum’ with ‘Twisted Dart’ juncus this year and it’s performing wonderfully. Syngenta Flowers’ Whispers series has a number of fine petunias, as well. The more I walk around, the more I notice ‘Whispers Red.’ But there are many other fine selections in the series.

The black petunia phase may be nearing a close, but I’m still impressed with the newest black petunia on the market: ‘Surprise Black Jack.’ Without a doubt, Dömmen’s Black Jack has been the best black petunia this spring. We have all been most impressed with its performance in the garden so far this year.

Dömmen’s Potunias have been a hit this year, as well. Papaya and Yellow are both outstanding. Their bright flowers are perfect with other combinations in containers.

We’re trialing 20-plus angelonias this summer and they’re in full bloom. There are, however, a handful of angelonias that stand out from the pack. They are:

– ‘Alonia Blue’

– ‘Archangel Blue’ and Pink

– ‘Carita Purple’ and Raspberry

– ‘Serena Pink’

– ‘Sungelonia White’

There are at least a dozen flags from our public open house in Syngenta’s ‘Carita Purple.’ This is by far the most outstanding summer snapdragon in the trials, and it has been for weeks.

‘Alonia Blue’ from Danziger has also been outstanding and was a winner last year, as well. Another great blue is Ball’s ‘Archangel Blue,’ which is taller than the other two but flowering well and worthy of my recommendation.

For a pink, ‘Archangel Pink’ has caught my eye, although ‘Serena Pink’ is also doing well. People really enjoy the color of ‘Carita Raspberry.’ It is quite different. Plants seem to stand out, but its habit is a little lanky and, if not for the unique color, would not be on this list. ‘Sungelonia White’ from Suntory Flowers is the best white in the trials at this point.

Hibiscuses

Fifteen or more hibiscuses are in the trial gardens, but again there are several standouts. They are:

– ‘Peppermint Schnapps’

– ‘Brandy Punch’

– ‘Carafe Bordeaux’

– ‘Cranberry Punch’

– ‘Royal Gems’

I love ‘Peppermint Schnapps’ with its handsome pink flowers lined with darker pink veins. It easily grows five feet tall. ‘Brandy Punch’ also has wonderful large pink flowers. It’s not as tall as ‘Peppermint Schnapps’ but can still reach four feet. The dark centers make a lovely contrast with the petals.

Two handsome dwarf selections are ‘Carafe Bordeaux’ and ‘Cranberry Punch.’ I love them both, and neither grows taller than three feet. However, the plant that has blown everybody away with its extra-large flowers is ‘Royal Gems.’ The flowers are the largest I have ever seen–as big as a satellite dish or perhaps two dinner plates. Unbelievable!

All-America Selections (AAS) has stepped forward with another first when promoting AAS Winners, this time in the form of cooking videos using vegetables/edibles that have performed extremely well in the AAS Trials. These days, a love of gardening is directly related to a passion for cooking. Tying the two together is a natural when marketing joys of cooking with fresh vegetables from the garden and farm market. After 82 years of conducting trials where only the best performers are declared AAS Winners, the organization now has more than 325 individual varieties that have been “Tested Nationally & Proven Locally.” It is some of these many varieties that culinary storyteller, entertainer and horticulture industry veteran Jonathan Bardzik will use in a series of five videos demonstrating cooking techniques with AAS Winning herbs and vegetables. “I am excited to partner with All-America Selections to show people across the country that AAS Winners perform […]

Greenhouse Grower’s lead editor, Laura Drotleff, and I got into a debate about why garden retailers, especially independent garden centers, snub marketing efforts from breeders and growers. She was very much on the breeders’ and growers’ side, expressing frustration about how limited retailers’ vision can be on the topic. I’ve reported on the garden retail side of the industry since 1998, about the same length of time Laura has reported on growers. I’ve heard a lot of retailer views on this, so allow me to share the most common reasons why retailers decline free marketing: Costs. While the marketing materials are free, and sometimes advertising, participating in these projects usually requires minimum orders. From a grower’s perspective, the minimum orders are reasonable. If garden stores promote a plant line, they need to have enough supplies to satisfy demand. From a retail perspective, if inventory reports show a plant line can […]

It is good to talk about production techniques, performance results and then to see how our friends garden. Diversity of plant material has always been a strength in American garden centers, and we should never run out of plants to get people excited. However, perhaps people are tired of Petunias or Callas or Geraniums, but we will never run out of options to put in front of them. One plant that is often overlooked is Pentas, a fabulous summer crop for late spring sales. These are heat-tolerant plants, and growing them below 65°F in the greenhouse results in significant delay. Fertility should be at least 150ppm nitrogen, but avoid ammonia in the fertilizer. Plants are best grown at a somewhat higher pH than usual, between 6.4 to 6.8. For best presentation, pinch out the center bud. Side flowers will bloom together, and plants will walk off the shelf. Garden centers […]

All-America Selections announced another group of edible AAS Winners for home gardeners, gourmet gardeners, farm-to-table growers, market growers and anyone interested in a unique, delicious addition to their vegetable assortment. These three winners are the first for the 2016 Garden Season. Additional winners will be announced this fall and winter as the 2015 trials conclude and the breeders meet specified criteria. The first group of AAS Winners for 2016 includes: Bunching Onion ‘Warrior’ (Regional Winner) Mizuna ‘Red Kingdom’ F1 (National Winner) Radish ‘Sweet Baby’ F1 (Regional Winner) All-America Selections has had bulb onions as award winners in the past, but ‘Warrior’ is the first bunching (or green) onion. Similarly, there have been green mustard AAS Winners, but never a red Mizuna (or Japanese Mustard). ‘Sweet Baby’ radish joins nine other radishes that are previous AAS Winners adding a violet colored beauty to an assortment of radishes that range from white […]

The Costa Farms team announced its late-season top performers in the 2015 Season Premier Trial Garden in Miami, Fla. Its research and development team has been working to grow and evaluate hundreds of varieties and have published their findings here. The plants you’ll find in the link have thrived in Miami’s late-spring conditions. Every spring, the research and development team trials 500 varieties of annuals, perennials and tropical plants from plant breeders around the world. All of the varieties were tested in the 2-acre trial garden. Varieties are assessed for abundance of bloom, crop uniformity and overall performance, which includes factors such as clean foliage, little to no pest damage and the plants’ overall habits and appearances. About 70 varieties scored as top performers during the evaluation period, which lasted from week five to week 19. Transplanting into the trial garden occurred at week 51, and plants were grown in 6-inch pots to finished […]
